This study aimed at the investigation of the mechanisms of acidogenesis, which is a key process during anaerobic digestion. To expose possible bottlenecks, specific activities of the key enzymes of acidification, such as acetate kinase (Ack, 0.23-0.99 U mg(-1) protein), butyrate kinase (Buk, < 0.03 U mg(-1) protein) and butyryl-CoA:acetate-CoA transferase (But, 3.24-7.64 U mg(-1) protein), were determined in cell free extracts of biogas reactor content from three different biogas reactors.

The key to acetate: metabolic fluxes of acetic acid bacteria under cocoa pulp fermentation-simulating conditions.

Project description:Acetic acid bacteria (AAB) play an important role during cocoa fermentation, as their main product, acetate, is a major driver for the development of the desired cocoa flavors. Here, we investigated the specialized metabolism of these bacteria under cocoa pulp fermentation-simulating conditions. A carefully designed combination of parallel 13C isotope labeling experiments allowed the elucidation of intracellular fluxes in the complex environment of cocoa pulp, when lactate and ethanol were included as primary substrates among undefined ingredients. We demonstrate that AAB exhibit a functionally separated metabolism during coconsumption of two-carbon and three-carbon substrates. Acetate is almost exclusively derived from ethanol, while lactate serves for the formation of acetoin and biomass building blocks. Although this is suboptimal for cellular energetics, this allows maximized growth and conversion rates. The functional separation results from a lack of phosphoenolpyruvate carboxykinase and malic enzymes, typically present in bacteria to interconnect metabolism. In fact, gluconeogenesis is driven by pyruvate phosphate dikinase. Consequently, a balanced ratio of lactate and ethanol is important for the optimum performance of AAB. As lactate and ethanol are individually supplied by lactic acid bacteria and yeasts during the initial phase of cocoa fermentation, respectively, this underlines the importance of a well-balanced microbial consortium for a successful fermentation process. Indeed, AAB performed the best and produced the largest amounts of acetate in mixed culture experiments when lactic acid bacteria and yeasts were both present.

Functionally redundant but dissimilar microbial communities within biogas reactors treating maize silage in co-fermentation with sugar beet silage.

Project description:Numerous observations indicate a high flexibility of microbial communities in different biogas reactors during anaerobic digestion. Here, we describe the functional redundancy and structural changes of involved microbial communities in four lab-scale continuously stirred tank reactors (CSTRs, 39°C, 12 L volume) supplied with different mixtures of maize silage (MS) and sugar beet silage (SBS) over 80 days. Continuously stirred tank reactors were fed with mixtures of MS and SBS in volatile solid ratios of 1:0 (Continuous Fermenter (CF) 1), 6:1 (CF2), 3:1 (CF3), 1:3 (CF4) with equal organic loading rates (OLR 1.25 kgVS m(-3) d(-1) ) and showed similar biogas production rates in all reactors. The compositions of bacterial and archaeal communities were analysed by 454 amplicon sequencing approach based on 16S rRNA genes. Both bacterial and archaeal communities shifted with increasing amounts of SBS. Especially pronounced were changes in the archaeal composition towards Methanosarcina with increasing proportion of SBS, while Methanosaeta declined simultaneously. Compositional shifts within the microbial communities did not influence the respective biogas production rates indicating that these communities adapted to environmental conditions induced by different feedstock mixtures. The diverse microbial communities optimized their metabolism in a way that ensured efficient biogas production.

Oxidative Fermentation of Acetic Acid Bacteria and Its Products.

Project description:Acetic acid bacteria (AAB) are a group of Gram-negative, strictly aerobic bacteria, including 19 reported genera until 2021, which are widely found on the surface of flowers and fruits, or in traditionally fermented products. Many AAB strains have the great abilities to incompletely oxidize a large variety of carbohydrates, alcohols and related compounds to the corresponding products mainly including acetic acid, gluconic acid, gulonic acid, galactonic acid, sorbose, dihydroxyacetone and miglitol via the membrane-binding dehydrogenases, which is termed as AAB oxidative fermentation (AOF). Up to now, at least 86 AOF products have been reported in the literatures, but no any monograph or review of them has been published. In this review, at first, we briefly introduce the classification progress of AAB due to the rapid changes of AAB classification in recent years, then systematically describe the enzymes involved in AOF and classify the AOF products. Finally, we summarize the application of molecular biology technologies in AOF researches.

Acetic acid bacteria (AAB) involved in cocoa fermentation from Ivory Coast: species diversity and performance in acetic acid production.

Project description:In this study, we investigated the diversity of AAB from fermenting cocoa and the production of acetic acid in response to various environmental conditions. Ribosomal 16S gene sequence analysis and PCR-RFLP showed a restricted microbiota mainly composed of Acetobacter pasteurianus, Acetobacter tropicalis and Acetobacter okinawensis sp., consistently found in all six regions studied. Meanwhile Acetobacter malorum, Acetobacter ghanensis and Gluconobacter oxydans were isolated as minor species in specific regions. The dominant species were mainly isolated in the first 72 h period of natural cocoa fermentation while the minor species were present toward the later stages. Acetobacter okinawensis, a newly isolated species, was able to yield an unusually high quantity, up to 62 g/L of acetic acid at 30 °C. However, a shift of temperature to 35 °C severely impaired acid production in most strains of this species. While acetic acid production increases for up to 6 days in Acetobacter okinawensis and Acetobacter pasteurianus, it decreases beyond 4 days in Acetobacter tropicalis strains. The production of acetic acid was strongly dependent on environmental conditions, with optimal production between pH 4 and 5, under ethanol concentration below 8% and temperatures above 35-40 °C, corresponding to conditions prevailing in the first half of fermentation process. Acetobacter tropicalis was more productive at higher ethanol concentration and Acetobacter okinawensis at low pH. Species diversity and different behavior of strains highlight the importance of valuable starter selection for well-controlled cocoa fermentation.

Characterization of lactic acid and acetic acid mutants in batch fermentation

Project description:Four C. thermocellum DSM-1313 derived strains were assessed using metabolite and DNA microarray tools in order to better understand carbon and electron flow within this organism. C. thermocellum is able to ferment cellulose into its fermentation end products L-lactate, acetate, formate, hydrogen gas, and ethanol, with the latter being the desired end product to be used as biorenewable fuel. In addition to the parent strain (genotype: hpt spo0A), strains with either or both of the genes encoding lactate dehydrogenase (ldh) and phosphate acetyltransferase (pta) deleted were studied. The strains used are a parent strain (M1726: genotype: hpt spo0A), and strains with either the gene encoding lactate dehydrogenase (M1629: hpt spo0A ldh) or phosphate acetyltransferase (M1630: hpt spo0A pta) deleted, or with both genes deleted (M1725: hpt spo0A ldh pta). Controlled batch fermentations using cellobiose as sole carbon source were grown for each strain, and samples in mid-exponential phase and at the time of carbon depletion were examined by DNA microarray. Four strains were grown each as three independent biological replicates (fresh batch of media was made before each run). Per fermentation, two samples were taken for DNA microarray analysis as was determined by the optical density: mid-exponential was defined as O.D. 0.4 (measured by Dasgip probe); point of carbon depletion was defined by both the maximum O.D. reached and observation that no base was added to the fermentation to control pH. In total, 4 strains x 3 fermentation x 2 time points per fermentor = 24 arrays. Parent strain was used as reference strain.

Deuteration of Indole Compounds: Synthesis of Deuterated Auxins, Indole-3-acetic Acid-d5 and Indole-3-butyric Acid-d5.

Project description:In this study, we describe a practical and facile synthesis of deuterium-labeled indoles via acid-catalyzed hydrogen-deuterium exchange. 3-Substituted indoles were efficiently deuterated through treatment with 20 wt % D2SO4 in CD3OD at 60-90 °C. A deuterium incorporation reaction of 3-unsubstituted indoles was accomplished through treatment with CD3CO2D at 150 °C. The in situ preparation of a 20 wt % D2SO4/CH3OD/D2O solution enabled a large-scale and low-cost synthesis of auxins, indole-3-acetic acid-d5 and indole-3-butyric acid-d5.

Schizosaccharomyces pombe can Reduce Acetic Acid Produced by Baijiu Spontaneous Fermentation Microbiota.

Project description:The spontaneous fermentation of alcoholic beverage is a bioprocess donated by microbiota with complex stress environments. Among various microbes, non-Saccharomyces yeasts have high stress tolerance and significantly affect the taste and quality of products in process. Although many researchers have focused on the influence of acid stress, the mechanism of non-Saccharomyces yeasts to tolerant stress remains unclear in microbiota. To bridge the gap, we constructed in situ and in vitro studies to explore the reduction pathway of acetic acid in non-Saccharomyces yeasts. In this study, we found Schizosaccharomyces pombe has special capacities to resist 10 g/L acetic acid in laboratory cultures and decrease the average concentration of acetic acid from 9.62 to 6.55 g/kg fermented grains in Chinese Maotai-flavor liquor (Baijiu) production. Moreover, Schi. pombe promoted metabolic level of mevalonate pathway (high expressions of gene ACCAT1, HMGCS1, and HMGCR1) to degrade a high concentration of acetic acid. Meanwhile, Schi. pombe also improved the concentration of mevalonic acid that is the precursor of terpenes to enhance the taste and quality of Baijiu. Overall, the synchronicity of reduction and generation in Schi. pombe advances the current knowledge to guide more suitable strategies for mechanism studies of non-Saccharomyces yeasts in fermented industries of alcoholic beverages.

Characterization of acetic acid bacteria in traditional acetic acid fermentation of rice vinegar (komesu) and unpolished rice vinegar (kurosu) produced in Japan.

Project description:Bacterial strains were isolated from samples of Japanese rice vinegar (komesu) and unpolished rice vinegar (kurosu) fermented by the traditional static method. Fermentations have never been inoculated with a pure culture since they were started in 1907. A total of 178 isolates were divided into groups A and B on the basis of enterobacterial repetitive intergenic consensus-PCR and random amplified polymorphic DNA fingerprinting analyses. The 16S ribosomal DNA sequences of strains belonging to each group showed similarities of more than 99% with Acetobacter pasteurianus. Group A strains overwhelmingly dominated all stages of fermentation of both types of vinegar. Our results indicate that appropriate strains of acetic acid bacteria have spontaneously established almost pure cultures during nearly a century of komesu and kurosu fermentation.
